双主键的Rest怎么搞

数据表的uid,mid字段为双主键，要实现rest怎么搞？

还有别的什么方法吗

自己解决了，

yii2是用,解决，原本传递id=10的，双主键为id=10,20。

    public function findModel($id)
    {
        if ($this->findModel !== null) {
            return call_user_func($this->findModel, $id, $this);
        }

        /* @var $modelClass ActiveRecordInterface */
        $modelClass = $this->modelClass;
        $keys = $modelClass::primaryKey();
        if (count($keys) > 1) {
            $values = explode(',', $id);
            if (count($keys) === count($values)) {
                $model = $modelClass::findOne(array_combine($keys, $values));
            }
        } elseif ($id !== null) {
            $model = $modelClass::findOne($id);
        }

        if (isset($model)) {
            return $model;
        } else {
            throw new NotFoundHttpException("Object not found: $id");
        }
    }
